In 2021, footprints were discovered along the shores of Lake Turkana in Kenya, providing important information about early human ancestors. These tracks, found in the Koobi Fora region, are 1.5 million years old. Researchers identified the footprints as belonging to Homo erectus and Paranthropus boisei, two species that lived in the Turkana Basin at the same time. The footprints were likely made in a short period, possibly within hours or days. This discovery offers a rare snapshot of ancient human behavior and movement. The proximity of the species suggests they may have interacted or lived near each other, giving scientists valuable insights into their lives. The analysis of the footprints also showed differences in the walking styles of the two species. Homo erectus walked similarly to modern humans, using a heel-to-toe stride. In contrast, Paranthropus boisei had a unique walking style with greater flexibility in the big toe. These findings help us understand how early human species adapted to their environments and evolved in different ways.
